CURRICULUM VITAE
Citro RobertaDr. Roberta Citro is an Associate Professor at the Department of Physics of the University of Salerno (Italy). In recent years she has matured professional experience in many-body techniques of low-dimensional systems and in quantum transport in nanostructures. She has recently established a new research team/activity on quantum transport in low dimensional systems. She completed her Ph.D in Physics at the University of Salerno (Italy) in 1998 defending a thesis on high-temperature superconductors. After her graduation, she was, first, a Post Doc Fulbright fellow at the Physics Department of Rutgers University (New Jersey, USA) where she collaborated with the Condensed Matter theory group, completing original works on the puzzling phase diagram of coupled spin chains by means of bosonizations and renormalization group methods. In 2007 she was a Marie Curie fellow under the EU's Sixth Framework Programme-Mobility Action at the Laboratoire de Physique et Modélisation des Milieux Condensés (LPMMC, CNRS) in Grenoble (FR) where she collaborated with Dr. Anna Minguzzi and Prof. Frank Hekking. Here she acquired knowledge in the field of atomic and molecular systems, working on the problem of non-equilibrium dynamics of a Bose gas subjected to a time-dependent perturbation. She has an active synergetic activity (Member of the organizing committees of five international conferences on quantum gases and a national meeting in superconductivity, member of the Doctorate collegium, referee of the APS and IOP Journals, of Nature and of national/EU research projects).

Dr. Roberta Citro is author of 125 articles published in international peer-reviewed journals (1 Rev. Mod. Phys., 4 Phys. Rev. Lett., 6 Rapid Communications, 3 Eur. Phys. Lett. and APL, 43 among Physical Review B and A). She has h-index 18 (from ISI web) and the total number of citations is more than one thousand. She has one book as co-editor published by the American Institute of Physics "Highlights in Condensed Matter Physics" (2003); she is co-editor of a topical issue of the European Physical Journal B entitle "Novel Quantum Phases and Mesoscopic Physics in Quantum Gases", vol. 68 (2009) and of the volume European Physical Journal ST, vol 217 pags. 1-220 (2013). She has delivered thirty-two invited oral contributions at international conferences. Prizes/awards: Italian Physical Society Award (1998) and Fulbright Award (1999).
